The Lowdown
Alright, Rusty here. Let's look at what's coming up for Lakey Pipe.
We've got a solid run of swell on the way, starting now and lasting for a good couple of weeks. The water is sitting at a pretty standard 80°F for this time of year, nothing unusual there. The standout period is the first week, with a long, powerful groundswell from the SSW that's going to be firing. This is a proper reef break, so it handles that long-period energy well, but it's not one for the beginners. When the swell pushes over 8ft, it's expert-only territory.
The action kicks off Friday the 7th of August morning with a clean 7ft SSW swell at 16 seconds. The combined energy is a solid 2725, and with that light cross-offshore breeze, it's looking excellent for experienced surfers. By Friday afternoon, the swell bumps up to 8ft (3217 energy), and the conditions stay clean. Saturday the 8th keeps the same energy going in the morning, but the afternoon gets a little cross-chop, so morning is the call.
Sunday the 9th and Monday the 10th are both excellent. Monday afternoon is the real gem of this first week: the swell jumps to 8ft but the period stretches to a very long 18 seconds, pushing the combined energy to 4276. The wind is a light cross-offshore breeze, making for some absolutely perfect, clean faces. This is the best on offer.
Tuesday the 11th, the swell hits 10ft (4447 energy). That's big and powerful, and the forecast says it's too big for this break. Leave it for the experts, or just watch.
The run continues through the middle of the month with clean 7ft to 8ft SSW swell, all with light winds. The best of this middle stretch is Thursday the 13th, with a 8ft swell and 17-second period, energy around 3683, and clean conditions all day.
We then get a slight drop in size around the 15th and 16th, with 4ft to 7ft swell, but it stays clean. The confidence is high for this whole first half.
Into the second week, the swell pulses again. Wednesday the 19th of August, another 10ft swell rolls in, this time from the SW with a 18-second period, energy hitting 5581. Again, too big for this spot. Thursday the 20th is still big, but Friday the 21st settles back to a perfect 8ft SW swell (3787 energy) with clean cross-offshore winds. That's your second-week standout, a proper session on the cards.
So, overall, Lakey Pipe is looking like a solid 16-day window. The best of the best is Monday the 10th of August afternoon, with that long-period groundswell and glassy conditions. Friday the 21st is also a top-tier call for the second week.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
